FRED HARRIS DANIELS, OF \VORCESTER, MASSACHUSETTS.

SPECIFICATION forming part of Letters Patent No. 585,622, dated June 29,1897.

Application filed April 12, 1897. Serial No. 631,727. (No model.)

State of Massachusetts, haveinvented certain new and useful Improvementsin Furnaces for Heating Ingots, Billets, Blooms, &c., of which thefollowing is a specification.

My invention relates to a furnace for heating ingots, billets, blooms,&c., and more particularly to an improved construction of the furnaceshown and described in United States Letters Patent, No. 234,162, ofNovember 9, 1880. In said patented furnace when the blooms have beenheated they are withdrawn from the side of the furnace by the attendant,so that the operation of the furnace is not automatic.

The object of my invention is to improve upon the construction of thefurnace shown in said patent and to make a furnace which is entirelyautomatic in its operation, so that an attendant is not required towithdraw the blooms from the furnace after they are heated, but the sameare automatically discharged from the side of the furnace preferablyonto an endless belt or track.

My invention consists in certain novel features of construction ofcertain parts of the furnace above referred to to make the sameautomatic in its operation, as will be hereinafter fully described.

Referring to the drawings, Figure 1 is a side view of a furnace of thedescription above referred to embodying my improvements. Fig. 2 is acentral longitudinal vertical section of the parts shown in Fig. 1. Fig.3 is a horizontal section taken at a point indicated by line 3 3, Fig.2. Fig. 4 is a transverse or crosssection taken at a point indicated byline 4 4, Fig. 3, looking in the direction of arrow o same figure. Fig.5 cor responds to Fig. 3, but shows a modified construction of thefurnace. Fig. 6 corresponds fireplace. 3 is the chimney, in thisinstance extending downwardly. 4 4 are two hollow bars or tubessupported on two walls or ridges 5, extending longitudinally in thefurnace. Water is passed through said tubes to prevent them fromacquiring too high a temperature, and upon these tubes the blooms areplaced crosswise, side by side, as shown by dotted lines 6 in Fig. 2,and are preferably pushed onto said tubes from a car 7 through anopening in the end of the furnace.

A hydraulic cylinder 18 may be used to push the blooms from the car intothe furnace and along the tubes.

As the bloomsare pushed along on the tubes 4 the front one, or the onenearest the fireplace end of the furnace, will be pushed off the tubes 4and onto the inclined tubes 8, (see Fig. 4,) which extend transverselyin the furnace at the end of the track formed by the tubes 4.

The tubes 8 are bent or inclined toward the opening 9 in the side of thefurnace, as shown in Fig. 4, which opening is provided with a hingeddoor 10. A roller 11 may be supported just below said opening, so thatthe blooms being pushed off from the tubes 4 will drop onto the inclinedtubes 8 and by reason of the inclination or slant of said tubes willautomatically pass along said tubes through the opening 9 in the side ofthe furnace and push open the door 10 and be discharged from the side ofthe furnace onto the endless track or chain belt 12, arranged in thisinstance under the furnace transversely thereof and in the path of theblooms as they are discharged through the opening 9 in the side of thefurnace.

In some cases the blooms are not heated sufficiently in every part inpassing along the tubes 4, and it is desirable to turn the blooms overto properly heat them. I therefore provide, just before reaching thedischarging end of the furnace, a sand bed 13, as shown in Figs. 5 and6, on which the blooms are discharged from the tubes 4. Through oneormore doors 14 in the side of the furnace the operator, by means ofhooks, can reach the blooms to turn or roll them over on said sand bed13 until they reach the end thereof, when they drop onto the extension 4of the tubes IOC 4, which are bent, as shown in Fig. 7, to cause thebloom to be automatically discharged through the opening 9 in the sideof the furnace.

The advantage of my improvements over what is shown in Patent N 0.234,162, above referred to, is that the furnace is made entirelyautomatic in the operation of heating the blooms, so that after beingpushed into the end of the furnace and heated by the flames passingunder and around them they are automatically discharged laterally fromthe side of the furnace without requiring the services of an attendantto withdraw them from the furnace.

It will be understood that the details of construction of the furnaceshown in the drawings and above described may be Varied, if desired, andparticularly the construction or arrangement of the tubes or hollow bars8, or equivalent devices, by means of which the blooms, &e., areautomatically discharged laterally from the side of the furnace.

I believe myself to be the first to provide means or mechanism forautomatically discharging laterally or in the direction of their lengththe heated blooms or causing them to be discharged from the side of thefurnace without the intervention of an attendant, as has been customaryheretofore.

Having thus described my invention, what I claim as new, and desire tosecure byLetters Patent, is-- 1. In a furnace for heating ingots,billets, blooms, &c., the combination with the 1on gitudinal way alongwhich the billets are advanced and on which they are supported whilebeing heated, of an inclined way within the furnace at the end of andextending crosswise of the longitudinal way to receive the billets asthey drop one by one from the longitudinal way, and a lateraldischargedoor on the prolongation of the inclined way through which thesuccessive billets as they descend the inclined way by gravity aredischarged end foremost, substantially as and for the purposeshereinbefore set forth.

2. In a furnace for heating ingots, billets, blooms, &c., thecombinationof the longitudinal way along which the billets are advancedand on which they are supported while being heated, the inclined waywithin the furnace extending crosswise of the longitudinal way toreceive the billets one by one and to direct them end foremost toalateral discharge-door, and a sand bed between the two ways,substantially as and for the purposes hercinbefore set forth.
